* Move the call to disable resize before placeNewBlock so that it is off when workspace resizeContents
gets triggered by placeNewBlock. This fixes a bug in rtl mode where the workspace was being resized
between when the block was added to the workspace and when it was moved to the proper location.
* Split the scrollbar and flyout out into their own SVG elements. They
are siblings of the workpsace SVG. This paves the way to make performance
improvements to workspace dragging.
Before, touchpads would give "smoother" scrolling by delivering lots of
mousewheel events with small distance changes. Because the code only
looked at the sign of deltaY, ten 5px scrolls would zoom 10x more than
one 50px scroll.
This change makes zooming with a touchpad more like zooming with a
mousewheel. On my laptop, a full-scale zoom (fully out to fully in) was
about a 5mm finger movement before, and is now about 3cm.
Fixes#758.
Existing text-editable fields don’t care (dropdown care, but are not
text-editable). But a note picker needs to set its value to 60 if text
is set to ‘C4’.
* Adds message references to message string interpolation, in the form of %{BKY_STRING}.
* Re-adding CONTROLS_IFELSE block using the new syntax, referencing to CONTROL_IF equivalents.
Improve performance of block dragging. This is a backport of the block drag surface from scratch-blocks. At the beginning of a block drag, blocks get moved to a drag surface which then translates using translate3d to avoid repainting the entire svg on every mouse move. At the end of the drag, the blocks are dropped back in the svg in their new position.
FieldDropdown now has onItemSelected(..) method to handle the menu item selection action. Variable renames and deletes are now handled here, instead of during validation.
Also fixes an issue deleting variables used by less than two blocks.
Fixes#723.
